Observation device



OBSERVATION DEVICE Filed NOV. 3, 1928 [N VENTOR I Edger A TTORNEYPatented Nov. 26, 1929 KARL BAUER, or BRONX, NEW YO K OBSERVATION DEVICEApplication filed November 3, 1928. Serial No. 316,993.

This invention relates toimprovements in observation devices for doors,walls or the like, so-called spyand peep-openings, or periscopesallowing an inspection of a person seeking admittance, or the deliveryof messages or the like, and presenting a pleasing appearanceharmonizing with the exterior of a door or wall in which the device isused.

It is the principal object of my invention to provide a device of thischaracter with a closing disc for the, observation opening automaticallyreturning into its closed position after each operation, and equippedwith an automatically operating locking device.

Another object of my invention is the'provision of a device of thischaracter of comparatively simple and therefor inexpensive constructionadapted to fit any door or wall, and firmly held in position thereon,allowing 20 an adjustment to suit the thickness of the material of dooror Wall and locking in its adjusted position.

A further object of my invention is the provision of an observationdevice of this type 25 equipped with a closing disc falling into itsclosing position by its own weight, while its opening movement issuitably limited.

These and other objects and advantages of my invention will become morefully known as the description thereof proceeds and will then bespecifically defined in the appended claims.

In the accompanying drawing, forming a material part of this disclosure:

Fig. 1 is an inner front elevation of my novel and improved observationdevice.

Fig. 2 is an end or edge view thereof, partly in section.

Fig. 3 is an outer or front elevation of the device.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawing by the samereference characters.

Referring to the drawing, theobservation device comprises an outertubular body 10 bevelled on its outer face, as at 11, and having aninner socket member 12 provided with an outer thread allowing theintroduction of the body through a suitable opening provided closedwork.

hand of the drawing.

in a door and wall at a convenient distance above the floor holding andsecuring thedevice therein.

Upon the threaded socket member 12a ring 13 is screwed allowing anadjustment of-the 1 device to doors or walls, etc., of any thickness ofmaterial such as for instance wood or metal. In its adjusted positionthe ring 13 is-securely held in place by means of suitable-fasteningmeans passed through openings 14.

The innerend of socket 12 has projecting therefrom at a point of itsface a pin 15 and a hook 16 spaced from said pin and below the same.

A disc 17 is pivotally attached, as at 18, 7, near its upper end to theinner end of socket member 12, and has near its pivot point a curvedrecess 19 adapted to be engaged by said pin 15, for limiting the inwardmovement of the disc 17 constituting cover for the central peepopening'in body 10.

A latch 20 is pivoted at its outer end, as at '21, to the disc 17 nearits outer periphery and in a-plane with hook 16. The opposite end oflatch 20 is hook-shaped, as indicated at 22, while a knob 23 projectingintermediate the ends of said latch 20 therefrom, allowsaconstantoperation of the same.

A guide or guard 24 allows the passage of the latch 20, and limits itsupward and downward movement.

I The front face ofdisc 17 is provided with a suitable grille 25 orother suitable open or The operation of my device will be entirely clearfrom the above description and on If it is desired to make anobservation, the resident disengages latch hook 22 from hook 16 bylifting latch 20 by means of knob 23 and rotates disc 17 about its hinge18, whereby the outer periphery hook 22 will automatically engage hook16 1 and lock the disc in its position in recess 19 to ensure thelocking.

It will be clear that the downward or up ward movements of the latchwill be suitably limited by guide or guard 24.

The disc 17 may have its outer face provided with an ornamental grilleas shown or the grille may be open work, and in this instance providedin socket 12.

It will be understood that I have described and shown the preferred formof my device as an example only of the many ways in which the same maybe practically constructed, and that I may make such changes in thegeneral arrangement and in the construction of the minor details thereofwithout departure from the spirit of my invention, as come within thescope of the appended claims.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent is 1. Observation device comprising a bodyhaving a centrally located peep opening and means for securing andholding said body to a support, said means allowing an adjustment to thethickness of the material of said support,- a cover for said peepopening pivotally attached to said body, and having a recess in itsperiphery, said cover allowing a turning about its pivot to uncover thepeep opening, a hook on said body, and means i on said cover forengaging said hook to lock said cover automatically'in its closing,posit10n after said dropping into closing posi tion under its ownweight, and a pin on said V cally upon the falling of said cover intoits peep opening closlng positlon under its own body adapted to engagethe peripheral recess of said cover.

'2. In an observation device ofthe character described, a body having acent-ralpeep opening adapted to be positioned in a door opening, meansfor adjustably holding said body in said opening, a cover eccentricallypivoted V on said body said cover having a peripheral recess, a pinprojecting from said body adapted toengage said recess for limiting theinward movement of said cover, the outward movement thereof beinglimited by the engagement of the outer periphery of said cover with saidpin, a hook on said body, a latch pivoted at one end to said cover at apoint opposite to said hook, a guard for limiting the vertical movementsof the latch, a hook on said latch opposite to its pivot point adaptedto engage said body hook automatiweight, and a knob on said latch foroperat ing the same to allow a turning of said cover about its pivotinto its opening uncovering position, and a grille formed with saidcover.
